Why Mac apps never get “closed”

Great answer to a common question. I've always liked the distinction between windows and processes in macOS, but many Windows users find it (understandably) odd — Windows power users sometimes feel that the mechanic robs them of control, in that clicking what they believe to be the "close application" button does not typically do what they expect.

I agree that neither approach is objectively right nor wrong.

I wonder what portion of users doesn't even know that you can/should quit mac application when you no longer use them. I frequently see people with dozens of active applications in their dock.

This is the converse of the situation on Android. I know many people who close android apps (by swiping them away in the app switcher) because they are afraid they will run in the background.
